At just $25 USD for a nice, 3 piece building that's fully painted (as well as 2 Buffer stops), this is a good value set. Stylistically, it matches the train station, which more or less works for just about any theater.
Like all of Battlefront's 2-story buildings, each floor and the roof is removable for dudes inside. I found the painting to be high quality with the brickwork especially looking quite nice.
The stoppers look alright and are maybe a bit redundant since you also get some with the curved track expansion, but it does give you some flexibility in setting up a nice train yard.
In conclusion, this is a good value set. If you already own both of the train track sets, but not the train station, it's worth picking up but isn't a "must buy". If you already own the station and both track sets, I'd say it's absolutely worth the $25. A solid kit that gives you a lot of flexibility in setting up a board! Keep it coming!
